They offer a mix of eye-catching aesthetics and unrivalled performance levels. They keep homes [warm and secure](https://www.harveyswindows.co.uk/blog/what-is-the-best-door-type-for-security-and-energy) while maximising the visual appeal and enabling modern living styles to be achieved even in the most confined of spaces.  Removing expanses of brickwork from the back of your house to replace with a stunning glass backdrop is a big project which must be carried out to strict structural standards and specifications.

The Harveys team will take care of all these aspects for you ensuring that your project will go smoothly and all requirements will be met.  [ Contact Us![right-arrow](https://www.harveyswindows.co.uk/hubfs/Harveys_Windows_Theme/Icons/arrow.webp) ](https://www.harveyswindows.co.uk/contact-us) ![](https://www.harveyswindows.co.uk/hs-fs/hubfs/Harveys_Windows_Theme/Gallery/bifold-upgrade-after-2.webp?width=1200&name=bifold-upgrade-after-2.webp) ![Enable Modern Living Aluminium Bifold & Sliding Doors](https://www.harveyswindows.co.uk/hubfs/Enable%20Modern%20Living%20Aluminium%20Bifold%20%26%20Sliding%20Doors.webp "Enable Modern Living Aluminium Bifold & Sliding Doors") ![](https://www.harveyswindows.co.uk/hs-fs/hubfs/Harveys_Windows_Theme/Gallery/bifold-upgrade-after-1.webp?width=1200&name=bifold-upgrade-after-1.webp) ![Guarantee-icon](https://www.harveyswindows.co.uk/hubfs/Harveys_Windows_Theme/Guarantee-icon.webp "Guarantee-icon") ## Full 10-Year Insurance Backed Guarantee ![Harveys Windows Before & After (1)](https://www.harveyswindows.co.uk/hs-fs/hubfs/Harveys%20Windows%20Before%20%26%20After%20(1).webp?width=2000&height=1310&name=Harveys%20Windows%20Before%20%26%20After%20(1).webp "Harveys Windows Before & After (1)") ## Benefits Renowned for its perfect combination of light weight and high strength, aluminium is the ideal material for sliding and folding doors, providing slim, elegant designs and outstanding performance. With a life-span measured in decades rather than years, together with extremely low maintenance requirements, aluminium has become the perfect choice for home owners. All our systems are designed with performance, looks and efficiency in mind, with each frame incorporating a ‘thermal-break’ to insulate doors against heat loss, raise the internal temperature of a house and help reduce the risk of condensation. Maintenance for aluminium systems is simple and straightforward, with a routine ‘wipe-clean’ all that is required to keep the products looking their best. With no requirement for re-painting or re-varnishing, aluminium windows and doors will never fade, deteriorate or rust.

Aluminium bifold doors operate using a concertina folding motion, neatly folding either inwards or outwards, at either end of the framework when opened fully. There also options that allow for the installation to fold open from the middle in two directions giving a central opening. As a result, they allow for incredible sight lines when fully opened, allowing for effortless entrance and exit between indoor and outdoor spaces. A traditional single door can be incorporated if needed to allow ease of access without opening the whole structure.

The maximum leaf height is 2600mm with 1200mm width, although in some situations they can go up to 3000mm maximum height. The site design wind load that the doors are subjected to will influence the maximum height and width [per panel] to which the doors can be manufactured. ### What is floating mullion on a bifold door? Floating mullions are used for aluminium sliding or bifold doors when the number of door panels is even (2,4,6) and they all slide/fold in one direction. The floating mullion adds an extra aluminium profile and sight line to the locking side of the door.   ### What is a floating corner on a bifold door? A floating corner is a popular feature in new-build properties or extensions where the ceiling has been reinforced to allow a completely open corner, usually a kitchen or reception room. With no corner pillar, the bifold can be installed with a floating corner post, which opens fully from the corner to both sides. This feature still delivers all the safety and security you would expect from a bifold door, while giving you uninterrupted views and that popular outside-in living. ### How secure are bifold doors? In addition to the inherent strength of aluminium, our bifold doors combine security hinges and multi-point locking systems with heavy duty rollers to provide security. Our bifold doors are tested to PAS 24, the industry standard in security, and certified under the Secured By Design scheme. ### What is the difference between aluminium bifold doors versus sliding doors? Both are used to open up inside spaces and make the most of external views. Bifold doors fold open in a concertina motion, and remain stacked at one or both sides of the opening. Sliding doors slide open using rails. With less frames, they bring in more light and panoramic views, while the actual opening itself is smaller than that of a bifold door. The choice depends on the style of property and the use of the room itself. ![Ultraframe Ultrainstaller logo small](https://www.harveyswindows.co.uk/hubfs/Ultraframe%20Ultrainstaller%20logo%20small.webp "Ultraframe Ultrainstaller logo small") [ Visit Ultraframes Website![right-arrow](https://www.harveyswindows.co.uk/hubfs/Harveys_Windows_Theme/Icons/arrow.webp) ](https://www.ultraframe-conservatories.co.uk/installers/harveys-windows-conservatories) ## Design Options ### Range Of Configurations Our aluminium sliding doors are available in a range of configurations with double or triple tracks for 2,3 or 4 pane options, allowing the panes to slide and stack up behind each other. These doors give the maximum in sight lines when closed. The slimline aluminium complements this design, delivering excellent visual appeal and  discreet hardware is offered to complement this feature. ![LOW MAINTENANCE](https://www.harveyswindows.co.uk/hs-fs/hubfs/LOW%20MAINTENANCE.webp?width=150&height=150&name=LOW%20MAINTENANCE.webp "LOW MAINTENANCE") ![Weather Resistant Bifolding Doors](https://www.harveyswindows.co.uk/hubfs/Weather%20Resistant%20Bifolding%20Doors.webp "Weather Resistant Bifolding Doors") ###  Weather Resistant Multiple weather resistant seals and thermally efficient glazing gives you maximum protection against the elements while you enjoy the view, and the high security locking mechanisms (including security deadlock and hook bolts) are designed to give you peace of mind. Stainless steel wheels ensure a smooth operation, and all doors are individually designed and manufactured to suit your specific needs, including the option of a range of dual colours so you can match a range of interior and exterior finishes. ### Versatile Our aluminium doors are as versatile as they are high performance. They can be installed as part of a home’s existing architecture or alongside the building of a bespoke Harveys orangery or house extension. The structural integrity of the profile allows them to be used to open up large areas without compromising on structural integrity or home security. ![Versatile Bifolding Doors](https://www.harveyswindows.co.uk/hs-fs/hubfs/Versatile%20Bifolding%20Doors.webp?width=150&height=150&name=Versatile%20Bifolding%20Doors.webp "Versatile Bifolding Doors") [![GET INSPIRED - VIEW OUR DOORS BROCHURE](https://no-cache.hubspot.com/cta/default/19927398/1ce5481a-0afe-4e80-9f59-54ed4c4c9e31.png)](https://cta-redirect.hubspot.com/cta/redirect/19927398/1ce5481a-0afe-4e80-9f59-54ed4c4c9e31) ![We Fully Guarantee](https://www.harveyswindows.co.uk/hubfs/We%20Fully%20Guarantee.webp "We Fully Guarantee") ## We Fully Guarantee #### These doors to keep looking good and working well for at least 10 years Bifold door projects quite often involve brickwork removal to widen the aperture across a building – this will involve local council building inspectors and a lintel to go across the top to give structural integrity – but don’t worry Harveys will take care of all of that for you.

Good customer service. Efficient, prompt, clean, pleasant. Customer Stories ### Excellent work from Harveys Windows I cannot praise this company enough. So efficient and friendly. Quality goods and quality service. Just remember to have plenty of tea on the go. Ham sandwiches and biscuits and the A Team will be very happy. Customer Stories ### Excellent service From start to finish they did a superb job. From going into the company and booking a survey to the fitters arriving at my property we were treated with friendliness and efficiency. The designer Ed Barton, the surveyor and fitters arrived on time, were extremely informative and fully involved with the task in hand. We are so pleased with our new front door, the finish is excellent and for the first time our hall stays warm. I would recommend this company highly. Customer in Leicestershire ### Seamless service and Quality craftsmanship From initial phone call to completion Harveys could not have been more helpful and client focussed. Offered solutions and had a great team, from demolition of existing to total rebuild. Everyone involved was professional, knowledgeable, polite and excellent at their part of the process. The project was on time and budget. I would highly recommend. Customer in Leicestershire ### Great company to deal with We chose Harvey’s to replace our conservatory roof and we believe we made the right choice. The surveyor was very thorough and the standard of workmanship was high. It took longer than we thought but it’s a huge conservatory and they encountered some appalling weather conditions and illness during the build. Everyone we dealt with was very helpful including staff at the office. Now it’s finished it looks great and several people have admired it and asked who we used. Needless to say we’rethrilled and we wouldn’t hesitate to recommend them. Customer in Leicestershire ### Beyond our expectations We wanted a conservatory adding to the back of our property but knew it wouldn't be a standard job due to the design of the house. Harvey's came along, put our minds at rest and gave us something that went beyond our expectations in terms of looks, materials used and workmanship. They definitely took the stress out of the whole project and gave us just what we wanted. Highly recommended! Customer in Leicestershire ### Excellent service and build Chose Harvey's to build us a small Orangery to square off a dog leg build by original home owner . From start to finish this project has been stress free . Harveys sorted all the paperwork, building regs . Surveys ect . Gave us week by week schedule so we could arrange when to be home . The weather was shocking but all the trades cracked on & still finished on time . The result is the wow factor . Just beautiful. Cannot wait to decorate it . Had a couple of snagging issues, but they were on it the next working day and fixed . All the team from tradesmen to staff were fantastic. We are using them again in the future and would 100 % recommend. Customer in Warwickshire ### Always great Had all new windows and front door, couldnt be more pleased. Always helpful, fitters were very tidy and great product. Have used Harveys before and wouldn't hesitate to recomnend or use them again Customer in Leicestershire [ View All Reviews![right-arrow](https://www.harveyswindows.co.uk/hubfs/Harveys_Windows_Theme/Icons/arrow.webp) ](https://www.harveyswindows.co.uk/reviews) ### Discover Inspiration & Quality ## Visit Our Showroom ** Opening Hours Monday - Friday 9:00 17:00 Saturday 10:00 - 13:00 ** Empire Road, Leicester, LE3 5HE We have a showroom close to Leicester city centre, where you can meet the team and see the products, so you can really satisfy yourself that you are getting what you want, and are dealing with the right people.
